While for classical thermal light resolution and second-order coherence are synonymous, we show that for quantum light beams reaching optimum precision second-order coherence and resolution become antithetical.engjournal articlehttp://dx.doi.org/10.1103/PhysRevA.81.065802http://journals.aps.org/open access535QuantumPhaseLightÓptica (Física)2209.19 Óptica Física
